Abstract
The utility model discloses a novel residual heat utilization device for an ascension pipe of a coke oven, which aims to solve the problems that the conventional residual heat utilization device for an ascension pipe of a coke oven is deformed and leaks easily. The novel residual heat utilization device comprises a plurality of sections of waste heat utilization devices which are connected in series, wherein each section of the residual heat utilization device is provided with an annular cavity composed of an outer tube and an inner tube, a spiral coil is wound in the annular cavity from top to bottom, a water inlet and a water outlet of the spiral coil penetrate the outer tube of the annular cavity to be connected with the outside world, and the annular cavity is filled with heat-conducting media; and when the novel residual heat utilization device works, the raw coke oven gas enters into the ascension pipe from the lower part of the ascension pipe, then heat is transferred to the heat-conducting media between the inner tube and the outer tube of the ascension pipe through radiation heat transfer and then transferred to the water pipe for the spiral coil wound therein through the heat-conducting media, and after entering into the series-connected residual heat utilization devices for the ascension pipe in sequence via the water inlet at the top end, the circulating water is partially or fully evaporated and finally enters into a steam drum from the last outlet, so that the purpose of residual heat reutilization is achieved. By adopting the novel residual heat utilization device, the problems of deformation, water leakage and the like are avoided, and the novel residual heat utilization device is convenient to install and maintain.
Description
Technical field
The utility model relates to a kind of coke oven residual heat using device, relates in particular to a kind of new Type Coke Oven tedge residual heat using device.
Background technology
Come out to enter about 800 ℃ of the raw coke oven gas of tedge from coke furnace carbonization chamber, coal chemical enterprise generally adopts traditional ammoniacal liquor spray pattern cooling, and a large amount of residual heat resources can't obtain utilizing.The eighties in last century, some enterprises adopt tedge gasification cooling device to reclaim heat, this device is formed water leg by urceolus and inner core, and corresponding water inlet, venthole and the sewage draining exit of being provided with, interior wall liner refractory brick in water leg and raw coke oven gas heat exchange, there is some problem in this device: 1, the impurity in the raw coke oven gas easily produces coking at the water leg root under the environment that colds and heat succeed each other, and influences the heat exchanger operate as normal; 2, water leg is subjected to factor affecting such as thermal stress and solder joint, service time of a specified duration can produce leakage problem, cause water in the whole drum carbonization chamber that bleeds when serious, cause security incident; When 3, sending water again after in particular cases cutting off the water, inner core is easily deformed by stress.Therefore a lot of enterprises are out of service in succession, removed this device, cause a large amount of tedge raw coke oven gas residual heat resources to be wasted.
The utility model content
The purpose of this utility model is to overcome the prior art defective, provides a kind of and can guarantee safety in production, prevents the new Type Coke Oven tedge residual heat using device of problems such as leakage, distortion.
The technical solution of the utility model is achieved in that new Type Coke Oven tedge residual heat using device, form toroidal cavity by urceolus and inner core, spiral coil is looped around within the toroidal cavity from top to bottom, the water inlet of spiral coil passes the toroidal cavity urceolus with delivery port and links to each other with the external world, fills heat-conducting medium in the toroidal cavity.
Further, be in series by at least two sections when described coke oven coke oven uprising tube residual heat using device is used, connect with ring flange between per two sections, the spiral coil delivery port of the preceding paragraph is communicated with pipeline with the spiral coil water inlet of next section.
Further, between spiral coil and water inlet and the delivery port be dismountable flexible connection.
Further, spiral coil does not directly contact with the tedge inner core, is fixed on inner core or the urceolus with pipe clamp.
Further, heat-conducting medium is tiny aluminium nitride powder.
The utility model characteristics:
When 1, working, raw coke oven gas enters in the tedge from the tedge bottom, by radiation heat transfer with the heat-conducting medium between the heat transferred tedge inner/outer tube, heat-conducting medium is coiled in heat transferred spiral coil water pipe wherein again, after recirculated water enters the coke oven coke oven uprising tube residual heat using device of series connection successively by water inlet topmost, partly or entirely vaporization enters drum from last outlet, realizes heat recovery.
2, the spiral coil water pipe of heat exchange does not directly contact with the tedge inner core,, the problem such as unevenly produce distortion that stress causes, leak of having avoided being heated.
3, the coke oven coke oven uprising tube residual heat using device adopts the multistage tandem, and it is convenient to install, overhaul.
4, be dismountable flexible connection between spiral coil and water inlet and the delivery port, can reduce the internal stress of spiral coil, avoid spiral coil to break.
5, heat-conducting medium adopts tiny aluminium nitride powder, Heat stability is good, and thermal conductivity is good, can anti-2000 remaining high temperature, high temperature down and iron and steel, water, oxygen reactionless, and loose powdered Heat Conduction Material available buffer pipe expansion avoids spiral coil and urceolus, inner core to break.
6, this device pressure that steams is 0.6-1.6MPa, by the adjusting pressure that steams, can control the temperature fluctuation of raw coke oven gas, has overcome the coking problem of tedge inner core.
